ABSTRACT
In this laboratory experiment, students will become familiar with the Seebeck effect, the Peltier effect, and thermal capacitors.They will also calculate heat energy of thermoelectric system. Students will learn how thermoelectric convertors operate and will convert heat energy into electrical energy.

LIST OF MATERIALS



PROCEDURE
  1. Watch and follow the instructions on the instructional video below.


  2. Measure the mass of the hot water
    masscup+water-masscup=masswater*


    Masscup = kg

    Masscup+water = kg

    Masswater = kg

  3. Celsius Degrees

  4. Measure the mass of the cold water
    masscup+water-masscup=masswater*


  5. Masscup = kg

    Masscup+water = kg

    Masswater = kg

  6. Celsius Degrees



  7. Take the thermoelectric converter out of the two cups.

  8. Celsius Degrees

  9. Celsius Degrees

  10. Calculate the heat energy of each cup.

    Celsius Degrees

    Celsius Degrees

    Given the "c" is a constant and is 4.185 J /g x C,
    calculate the heat energy of the
    BE SURE TO CONVERT KG TO GRAMS!! *


    hot cup = J

    cold cup = J

  11. Mix both cups of water together and place the thermoelectric converter into the mixed water cups.



  12. Remove the thermoelectric converter from the water and let it cool to room temperature.

  13. Watch and follow the instructions on the instructional video below.
